CAZyme prediction in ascomycetous yeast genomes guides discovery of novel xylanolytic species with diverse capacities for hemicellulose hydrolysis

Biotechnology for Biofuels, 2021
Background Ascomycetous yeasts from the kingdom fungi inhabit every biome in nature. While filamentous fungi have been studied extensively regarding their enzymatic degradation of the complex polymers comprising lignocellulose, yeasts have been largely ...

Evaluation of new xylanolytic-producing isolates of Aspergillus from Misiones subtropical rainforest using sugarcane bagasse

Arab Journal of Basic and Applied Sciences, 2019
Xylanases hydrolyse efficiently the xylan component of hemicelluloses into single xylose monomers. Hence, these enzymes are suitable to be applied in the bioconversion of lignocellulosic wastes such as sugarcane bagasse to improve the bioethanol process.

Isolation of butyric acid producing xylanolytic bacteria from the rumen

Acta Agriculturae Slovenica, 1997
Xylans are major components of plant materials and a lot of the rumen bacterial species possess enzymes with xylanolytic activity. Recently we isolated eight xylanolytic strains from the rumen and determined metabolic end products, sugar fermentation ...

The influence of substrate concentration and growth phase on expression of Butyrivibrio sp. Mz5 endoxylanases

Acta Agriculturae Slovenica, 2000
Butyrivibria represent a significant proportion of bacterial isolates from different ruminants. The strain Butyrivibrio sp. Mz5 was originally isolated from the rumen of a black and white Frisian cow. It possesses very high xylanolytic activity, at least

Production of xylanolytic enzymes by Penicillium janczewskii

Bioresource Technology, 2010
The production of extracellular xylanase, beta-xylosidase and alpha-l-arabinofuranosidase by the mesophilic fungus Penicillium janczewskii under submerged cultivation was investigated with different carbon sources. Optimization steps included studies of carbon source concentration, temperature of cultivation and initial pH of culture medium.

Symbiotic Behavior during Co-culturing of Clostridium thermocellum NKP-2 and Thermoanaerobacterium thermosaccharolyticum NOI-1 on Corn Hull

BioResources, 2014
The symbiosis of co-culturing between Clostridium thermocellum NKP-2 and Thermoanaerobacterium thermosaccharolyticum NOI-1 is described. An efficient biomass-degrading enriched culture was isolated from soil that contained two different bacterial strains

The xylanolytic enzyme system from the genus Penicillium

Journal of Biotechnology, 2006
In nature, there are numerous microorganisms that efficiently degrade xylan, a major component of lignocellulose. In particular, filamentous fungi have demonstrated a great capability for secreting a wide range of xylanases, being the genus Aspergillus and Trichoderma the most extensively studied and reviewed among the xylan-producing fungi.

Yeasts Have Evolved Divergent Enzyme Strategies To Deconstruct and Metabolize Xylan

Microbiology Spectrum, 2023
Together with bacteria and filamentous fungi, yeasts actively take part in the global carbon cycle. Over 100 yeast species have been shown to grow on the major plant polysaccharide xylan, which requires an arsenal of carbohydrate active enzymes. However,

Activity-Based Protein Profiling for the Identification of Novel Carbohydrate-Active Enzymes Involved in Xylan Degradation in the Hyperthermophilic Euryarchaeon Thermococcus sp. Strain 2319x1E

Frontiers in Microbiology, 2022
Activity-based protein profiling (ABPP) has so far scarcely been applied in Archaea in general and, especially, in extremophilic organisms. We herein isolated a novel Thermococcus strain designated sp.
